At present, acoustic maps are used in management tasks of assessing the acoustic climate of the environment. The methods of modeling and simulation of noise assessment indices are used for this purpose. These indicators represent the quantitative spatial distribution of the sound level. Research on the perception of sounds has been carried out for many years and it has been found out that subjective acoustic impressions are of significant importance. This paper proposes a quantitative and qualitative approach to the assessment of noise in the urbanized environment using acoustic maps. The features of sound quality and their importance in the modeling of noise annoyance assessment have been described. Acoustic measurements were made on the example of the selected case study in the environment. The results of modeling physical indicators of road noise in the environment with the use of acoustic maps are presented. Based on the registered acoustic measurements, the results of the sound quality features of the acoustic signals in the time and frequency domain are presented below. The determined values of sound quality features are a valuable source of information in the field of noise perception assessment. A model for assessing road noise has been proposed. It includes sound quality features which can be used in acoustic maps. As part of the discussion of the results, it was found that the obtained results of quantitative and qualitative analysis of the acoustic signal parameters can be the basis for the development of the road traffic noise annoyance assessment model using acoustic maps technology.
